Description

Technical Field

[0001] The present invention belongs to the technical field of belt transportation sampling, and particularly relates to a sampling device applied to a belt. Background Art

[0002] At present, manual sampling with a sampling shovel on the belt conveyor has been used for belt unloading sampling. During the unloading process, it is necessary to continuously pay attention to the belt running status, flow rate, etc. The labor intensity is high, and there are also certain safety risks for the sampling personnel to sample with a sampling shovel on one side of the belt. Sampling with a sampling shovel manually on the belt conveyor is relatively arbitrary and has low representativeness.

[0003] In order to overcome the above-mentioned sampling defects, the prior art has designed operating equipment for sampling in the middle of the conveyor belt. However, in the middle sampling state, when the transportation volume is large, only the upper layer of concentrate on the belt can be sampled, and the lower layer cannot be sampled, resulting in a slight error in sampling.

[0004] In view of the above factors, a sampling device applied to a belt is provided, which improves the labor efficiency of sample collection, reduces the unstable factors of manual sampling quality, and reduces the labor intensity of operators. Summary of the Invention

[0005] The purpose of the present invention is to provide a sampling device applied to a belt to solve the problems raised in the above background art.

A movable sampling assembly is arranged in the fixed bin. The sampling assembly includes a plurality of sampling bins arranged in parallel. The front end of the sampling bin is provided with an open baffle structure, and the rear end of the sampling bin is connected to a conveying pipe;

[0007] The conveying pipe is connected to a receiving bin. The receiving bin is detachably connected to the sampling assembly. The sampling bins are arranged in a stepped manner along the transverse direction of the belt head pulley, and the height of the sampling bins is not higher than the height of the materials on the transmission belt;

The rear end of the mounting frame is connected to a hydraulic cylinder. The output end of the hydraulic cylinder is connected to the mounting frame, and the rear end of the hydraulic cylinder is fixed on the fixed bin.

[0013] Further, the sampling bin is horizontally arranged or inclined, and the inclination angle is 15 - 30 degrees.

[0014] Further, the receiving bin has a barrel structure. The receiving bin is located in a positioning groove fixedly provided on the mounting frame. The shape of the positioning groove is square with the barrel structure, and the height of the positioning groove is less than one - third of the height of the barrel.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0033] Among them, one side of the fixed bin close to the head pulley 7 of the belt is open, and one of the front and rear end faces of the fixed bin is connected to the side door 8 by a hinge. By setting the side door 8, it is convenient for maintenance and taking the receiving bin during use.
